Add condition to adata.obs

[spatts14]

Currently adding condition to adata.obs like this:

adata.obs["condition"] = (roi_name.split("_")[0] if roi_name.split("_")[0] in ["IPF", "COPD", "PM08"] else "Unknown" ```

However that only works for my data, so want to remove the hard coding

Ideas:
Could add a variable list the user inputs in the config? e.g condition_names = ["IPF", "COPD", "PM08"]
However still would need the condition to be the first word in the ROI
Can I change the code so it looks for the word in the ROI?
